Take the help of some other computer, insert the storage device. If the autoplay option doesn’t appear, move to the My Computer or This PC. 

The storage bar will appear in the drive, denoting how much storage space is consumed. If the color is red, then the storage device is running out of memory, and it’s not that critical issue at all. Now, right-click on the drive to access the properties. 

Check the storage type. Generally, the tech experts suggest that the NTFS format is very much suitable to create a stable bootable storage device. If the format is FAT 32, change it to NTFS and perform a Quick Format. The process will take just a few seconds to complete. 

Lastly, with the help of a third-party application, transform the storage device into a bootable by burning the OS image file. Hopefully, this procedure will definitely work.
